P-14 (5N84 «OBORONA», 5N84A) RADAR MODERNIZATION

OVERVIEW Modernization of early-warning VHF radar 5N84A (5N84, 44Zh6 or P-14) offers the best (in terms of efficiency/cost ratio) alternative to restoration or repair of legacy prototypes. As a result of modernization the radar’s detection performance is efficiently improved. Modernized radar features automatic tracking capability as well as data receiving from other radar sensors. Data can be exchanged over a variety of communication channels.DEPTH OF MODERNIZATION: Radar’s equipment cabin has been fully modernized. Metric band is preserved, however the number of working frequencies has been sufficiently increased from 4 to 200, the capability of instantaneous electronic frequency agility has been added as well. The radar transmitter and receiver feature solid-state components only. Transmitter has a modular design which provides ‘soft-failure’ redundancy: failure of individual module leads to partial performance degradation.Antenna-mast assembly is equipped with the new asynchronous motor drives controlled by frequency inverters. Modernized 5N84AMA radar remains a two-dimensional system and it is used to find azimuth and range.Altitude can be obtained by interfacing modernized height-finding radars. Parameters of the transmitted signal as well as parameters of the signal processing after reception can be set at the operator workstation, while secondary processing and tracking are performed at remote workstation. Both workstations are installed in the equipment cabin. As an option, ground interrogator can be controlled in auto- and semiautomatic modes with assigning aircraft state identification status. All air situation is automatically recorded with playback capability in passive and interactive modes. Modernized 5N84AMA radar features efficient protection against pulse interference and active jamming. Level of interference is continuously monitored and graphically represented to operator. Jamming protection is achieved through expansion of the dynamic range of the signal processor and capability of electronic frequency agility. Passive interference is rejected through digital adaptive MTI and generation of clutter map. Equipment of 5N84AMA can be installed on a semitrailer or in two standard sea containers mounted stationary or on a vehicle.
